Cl. 53-390 12 Claims ABSTRACT OF THE DISCLOSURE A bag dispensing device having a repository for a continuous flexible tube in the form of a supply roll, and having an upright tubular housing with a wall constituting a table pivotally supported to permit said table to be moved from upright bag filling position into bag discharging position extending transversely outwardly of said housing. A tube section can be pulled out from the roll through guiding means at the base of the housing into said housing, and folded at its upper end over the upper edge of the housing, while the lower end of the tube section is closed by said guiding means. A tube severing means is mounted on the table at its outer end.

The present invention relates to a device for dispensing tube sections from a continuous tube of flexible material, for supporting the dispensed sections in the form of fillable bags, and for severing the filled bags to permit handling thereof as separate units. The device of the present invention can be employed, for example, in households for packaging food for storage or for subsequent consumption, and for collecting garbage, laundry and the like, in post ofiices for collecting mail for shipment to different postal destinations, in offices and industrial plants for wastes, in hospitals for surgical or medical implements for heat sterilization, and in other establishments for many other uses where an inexpensive disposal bag is desired.

Continuous lengths of tubular plastic materials free from transverse bag-defining seals are commercially available and in certain respects, are more desirable than the type of continuous lengths of tubular plastic material, which are divided into bag sections of definite lengths by transverse seals, mainly because they are less expensive,

easier to sever and more convenient to handle, and because the lengths of the sections dispensed therefrom can be varied to form bags of any desired length.

7 One object of the present invention is to provide a new and improved device for dispensing lengths of flexible tubular material from -a continuous supply of this material easily and neatly in inflated bag form of selective length and in position for convenient filling, with minimum of manipulable effort.

Another object of the present invention is to provide a new and improved device for dispensing lengths of flexible tubular material from a continuous supply of this material and in fill-able bag fonm, and for quickly, conveniently and efficiently severing the filled bags.

A further object of the present invention is to provide a new and improved device of the general type described, which is adaptable for a variety of household, industrial, governmental, commercial and hospital uses, where bag dispensing means are required.

Referring to the drawings, the device of the present invention is shown for the purpose of illustration, made of plastic for use in small sizes for household or other small scale use, but can be made of any size andof any material, such as metal, in accordance with its intended use. The continuous flexible tube 10 (FIG. 9) to be dispensed, is made of suitable plastic film material, usually employed for making disposable bags, such as polyethylene or the like, and is made of two flat panels 11 arranged face to face and joined by infolded accordian side sections or pleats 12, permitting said tube to be expanded from flat rolled form into substantially rectangular form. The continuous tube 10 in flattened collapsed condition shown in FIG. 9, and free from any transverse subdividing seals, is wound on a cardboard core 13 to form a roll 14, suflicient to form hundreds of bags.

The gauge of the tube material usually is 1 to 1 /2 mils and for household and similar small scale use can be up to 3 mils, and to form heavy bags for governmental or industrial uses, can be from 3 to 6 mils.

The device of the present invention for forming and dispensing bags from the tube supply roll 14 comprises a lower base section 15 defining a repository for the roll, and an upper section 16 defining the bag forming, supporting and severing part of the device. The base section 15 comprises a base plate 17 and a rectangular box frame 18 on said base plate formed with a semi-cylindrical trough 20 for receiving the supply roll 14 snugly therein but with enough freedom to permit the roll to rotate and unwind easily by the pulling action on the free end section of the rolled tube 10. During dispensing operations, the supply roll 14 is turned in the trough 20 by pulling of the free end section of the tube 10, and to reduce the present invention are apparent from the following de- I friction on the supply roll during this operation, there is formed in the inside of the trough a pair of circular ribs 21 on which the roll rests and over which it rides as it rotates.

The upper section 16 of the dispensing device has a lower rectangular tubular frame 22 and an upper rectangular tubular housing 23 provided with relatively movable walls, and serving to support a dispensed section. of the tube 10 in inflated bag-forming position for filling..The lower rectangular frame 22 is dimensioned to fit snugly over the base box frame 18 with a friction fit, free enough to permit this frame 22 to be easily slipped off said base box frame 18, and to be easily slipped telescopically over said box frame 18 for tube supply replenishment, but tight enough to be retained in operative position during bag dispensing and severing operations.

The upper rectangular housing 23 comprises a deep channel 24 having parallel side walls 25 and an intercon-t necting rear wall 26, these walls being rectangularly arranged and forming continuous extensions of the correspofidin gwalls of the lower-tubular frame 22. The housing 23 also comprises a tiltable or hinged table 27 extending across the open side of the channel 24 and pivotally secured to the side walls 25 of said channel by means of pivot pins 28. This table 27 is channel-shape and comprises a front wall 30 and side flanges 31. The pivot pins 28 pass through holes 29 in these side flanges 31, and the side walls 25 of the channel 24 embrace the side flanges with a snug slide fit. In upright position of the tiltable table 27 shown in FIGS. 2 and 3, this table forms with the channel 24 the rectangular tubular housing 23, and in this upright position of the table, the housing supports a dispensed section 33 of the tube in inflated position for filling as shown in FIG. 3 and as will be described more fully hereinafter.

' In operation, to form a bag and support it in inflated fillable position, a section 33' of the tube 10 is pulled into the housing 23 from the tube roll 14, and the upper end of this tube section is spread and folded over the upper edge of the housing, while the lower end of this section is restricted and confined to close this lower end. To close the lower end of the pulled or dispensed tube section 33, the table 27 is formed at its lower end with a foot extension 35 having two angularly offset successive sections 36 and 37. The inner foot section 36 near the heel of the foot 35 has an elongated slot 38 through which the flattened tube 10 from the supply roll 14 is threaded. The outer foot section 37 has a similar elongated slot 40 through which the flattened tube 10 from the supply roll 14 is threaded. The dispensed section of the tube 10 thereby passes upwardly almost vertically from the supply roll 14 through the slot 38, over the foot 35 and downwardly through the slot 40 along the underside of the forward part of the center foot section 37, and upwardly across the outer edge of this outer foot section, as shown in FIG. 3.

To assure sealing of the lower end of the bag formed in the housing 23 against escape of the contents beyond said end, there is an apron or platen 45, integral or otherwise secured to the rear wall 26 of the channel 24 and extending below and in face to face contact with the outer section 37 of the foot 35, so that the section of the tube 10 passing underneath the forward part of the outer foot section 37 is sealably confined between this forward part of the outer foot section 37 and the platen 45. The platen 45 has a rib 46 located as to be spaced only a small distance from the outer edge of the outer foot section 37 in upright bag filling position of the tiltable table 27 shown in FIG. 3, to confine the lower end of the tube section 33 in this region, while permitting the tube 10 to be pulled through this confining region.

The platen 45 serves not only as a means for restricting and sealing the lower end of the tube section 33 dispensed in the housing 23 but also serves as a bearing for the foot 35 of the tiltable table 27, permitting said table to be pressed inwardly by finger manipulation from the upright position shown in FIG. 3, about the axis of its pivot supports 28, and into the channel 24, against resilient action to be described. This inward pressing of the table 27 reduces the dimension of the mouth of the housing 23 between the channel wall 26 and the table 27, and permits thereby the upper section of the dispensed tube section 33 to be folded easily over said mouth. To permit this inward pressing of the table 27, the section 47 of the foot 35, although reinforced with ribs 48, is still weak enough to flex resiliently when the table is pressed inwardly in the channel 24. The support afforded by the platen 45 permits this resilient flexing of the table foot 35.

While the table 27 is pressed inwardly into the channel 24'by one hand as described, the other hand can conveniently reversely fold the upper margin of the tube section 33, which has been pulled into the housing 23, over the upper edge of said housing. Upon release of inward pressure on the table 27, the table under the action of its inthe platen 45, is restored into upri ght bag filling position shown in FIG. 3. The mouth of the bag is thereby inflated into taut condition, assuring thereby the retention of the bag in upright position in the housing 23 during filling, as shown in FIG. 3.

In order to be able to gage the safe extent to which the table 27 should be tilted inwardly into the channel 24 to prevent excessive flexing of the foot 35 of said table, the side walls 25 of these channels at their upper ends and forward margins are provided with notches 50 defining gage edges 51. The table 27 is tilted inwardly by pressing a thumb against the upper end of the table on the side opposite a notch 50, until the front wall 30 of said table in the region of the thumb is substantially flush with the gage edges 51.

Instead of resiliently flexing the foot 35 of the table 27 by the inward pressing of the table as described,'-the foot may be rigid with the table, so that it does not flex, but the platen 45 may be able to yield angularly resiliently about the base near where it connects into the rear wall 26 of the channel 24, when said platen is pressed downwardlyby the inward pressing of the table 27 into the channel and the table can be restored into upright position upon release of finger pressure by the inherent resiliency of said platen at said base.

Also, as far as certain aspects of the invention are concerned, both the foot 35 of the table 27 and the base of this platen 45 may resiliently yield and flex upon inward pressing of the table into the channel 24.

The table 27 is tiltable outwardly about the axes of the pivot pins 28, to form a downwardly and outwardly sloping chute and platform, as shown in FIG. 8, with its wall 30 resting on the upper edge 52 of the front wall of the tubular frame 22, as shown in FIG. 8 and as shown in position A in dot-and-dash lines in FIG. 3. The table 27 is tilted in this downward sloping position after the bag in the housing 23 has been filled, and it is desired to close and sever this bag and pull the next succeeding section 33 of the tube 10 from the supply roll 14 to form the next fillable bag in the housing.

The table 27 carries bag severing means 59 at its upper end, designed to prevent possible injury by accidental contact therewith, and separable from the table. This bag severing means 59 comprises two similar knife retaining plates 60 and 61 of substantially rectangular shape, having respective deep notches 62. Plate 60 has four pins 63, two on opposite sides of its notch 62 and the plate 61 has four corresponding holes 64, two on opposite sides of its notch 62, to permit impalement of said plate 61 on said pins 63, with the two plates in registry.

Two double-edge wafer razor blades of the type ordinarily used for shaving are impaled on the four pins 63 of the plate 60. The two rows of pins 63 on opposite sides of the corresponding notch 62 are inclined towards each other and are located, so that when the two razor blades 65 are impaled thereon, the confronting cutting edges 66 of the two blades converge away from the open end of the corresponding notch 62 and intersect in said notch; any element thereby inserted downwardly in the notches 62 in the severing unit 59 will be severed by the converging and intersecting cutting edges 66 of the razor blades 65. The notches 62 are narrow enough to prevent the fingers of the user from entering the notches accidentally and being cut by the blades 65.

In assembling the bag severing means 59, the two razor blades 65 are impaled on the pins 63 of the plate 60, and the plate 61 is impaled on these pins and over the blades to clamp the blades 65 between said plates, so that the plates form a holder for said blades. The unit pack 59 so formed is removably attached to the table 27. To removably receive the severing unit 59, the upper section of the front wall 30 of the table 27 is formed with a pocket recess 70 having a notch 71 corresponding in size and shape to the notches 62. The pocket recess 70 and its notch 71 are dimensioned to slidably and snugly receive the severing unit 59 with the notches 62 in registry with the recess notch 71.

In removably mounting the severing means of the present invention in operative position, the two plates 60 and 61 are assembled in impaling relationship through the pins 63 and the holes 64 with the razor blades 65 impaled on said pins and sandwiched between said plates. The assembly is then slid into the table recess 70. To lock this blade assembly in the table recess 70, a stud 73 with a square head 74 passes through the notch 71 in said recess and through aligned holes 75 in the plates 60 and 61, with its head retained snugly in said notch against turning, and screws into a knob 76 on the front side of the table 27 bearing against a panel 77 defining the front wall of said recess.

The severing means described permits the means to be disassembled to permit the razor blades 65 to be reversed to present fresh edges thereof into cutting positions or to replace dull blades.

In the operation of the tube dispensing device of the present invention, the device for normal operations is set with the table 27 in upright position shown in FIGS. 2 and 3. In this position, a section 33 of the tube has already been pulled out of the supply roll 14 and is in upright filling position in the form of an inflated bag in the housing 23, with its upper end expanded into rectangular shape and folded reversely over the upper edge of the housing, and its lower end closed and sealed by the cooperating foot 35 and platen 45, as shown in FIGS. 2 and 3. In this inflated position of the tube section 33, this tube section can be filled with material to be bagged for storage, transportation or disposal, according to the use to which the dispensing unit is to be put. After the tube section 33 has been filled, the reversely folded mouth of the tube section in the form of a filled bag is removed from the upper edge of the housing 23, and closed either by tying the mouth of the bag into a knot 78, or by gathering the mouth of the bag and twisting tightly to form a closure neck, and applying a wire grommet to this neck. This grommet may be of the well-known type consisting of an open annular rigid wire overlapping and gripping the neck of the bag by means of a suitable pinching grommet applying tool.

After this operation, the table 27 is pulled down into downwardly sloping bag discharging position with the table supported on the upper edge 52 of the front wall of the tubular frame 22, as shown in FIG. 8. In this position of the table 27, this table serves as a chute, permitting the filled bag to be pulled down easily along the table and into hanging position with its closed end at the bottom. The other end of the filled bag is then twisted to reduce the thickness of the neck for free passage through the severing unit 59, and the resulting restricted bag neck is passed through the cuttingnotches 62 and 71 and across the converging cutting edges 66 of the blades 65, as shown in FIG. 8, thereby cutting the twisted neck and severing the filled bag from the succeeding tube section 33. The filled bag pulling operation described also serves to pull the next succeeding tube section 33 from the supply roll 14 along the sloping table 27. Afterseverance of the filled bag, the cut end of the bag can be closed by tying this end into a knot or by applying a grommet thereto. The table 27 is then restored into upright position to form the housing 23, and the new section 33 of the tube 10 in this'housing can be pulled according to the length of the bag desired. The table 27 is then pushed inwardly into the channel 24 against inherent resilient action described to restrict the width of the mouth of the housing 23, and the upper margin of this tube section 33 is folded reversely over the restricted mouth of the housing. Upon release of the table 27, the table will return outwardly to upright position in which the mouth of the housing 23 is fully expanded, thereby stretching the mouth of the tube section 33 into taut expanded position for bag filling operations and will be retained in this position by the taut connection of the mouth of this tube section to the mouth of the housing 23.

With the dispenser construction described, permitting the use of continuous tube in roll or spool form, the cost of sealing the tube, of cutting the tube into bags of fixed sizes, and of handling the bags is eliminated.

Also, with the dispenser construction described, bags of selective lengths can be formed and dispensed, and the amount of manipulations required to form and dispense bags is reduced, since the operation of closing and completing a filled bag effects automatically the placing of a next succeeding section of the tube supply into position for filling.

Furthermore, the use of supply rolls instead of individual separated bags, discourages pilfering in such places as industrial plants, commercial houses, such institutions as hospitals and the like.

Also, since the bag is set up and supported in expanded upright position for filling by the device of the present invention, the user has both hands free to fill the bag.

The dispensing device of the present invention can be employed for household use, as for example, to store kitchen left-overs, to package sandwiches, as a wastebasket, and to collect garbage. Where the bags are to be used to store kitchen left-overs, they may be made of a polymer which will withstand boiling water for heating without disintegrating. For example, for the bag material, certain copolymers of polyolefins, containing such polymers as polybutene may be used.

Also, the dispensing device of the present invention may be employed in hospitals, and where the bags are to be used to sterilize equipment and instruments, the bag material is made of a plastic which can withstand sterilization heat.

The dispenser device can also be employed in hotels and restaurants for collecting waste and garbage, in schools for garbage and for waste from lunch boxes, etc., in post offices for collecting mail intended for different destinations and as waste-baskets, in banks and oflices for waste-paper, on boats and yachts for disposal of rubbish, the bags being puncturable to cause the filled bags to sink to the bottom of the water, without dispensing the contents of the bag, and in laundromats for holding wet wash and the like.
